345 – Tier 3

    
• Founded in 1925, Caterpillar established the standard for tractors and construction equipment from the outset. Over the years, the company’s leaders have gained a great deal of knowledge about what works and what doesn’t. Caterpillar has grown alongside its customers, developing new products for hardworking individuals who want to push the limits. With that history comes innovation, change, creation, and learning. Caterpillar has partnerships across multiple industries and companies, continually developing and refining its understanding of how equipment should operate. Our commitment to designing and building the world’s best equipment is evident in every single product.
    
• The latest cab design is outfitted with an ergonomic seat, touchscreen display, climate control, noise insulation, and vibration reduction, helping reduce fatigue while allowing the operator to stay on task.

Build Number: 07H

    
• Work up to 3300 m (10,830 ft) above sea level.
    
• Powerful swing torque easily handles changes in momentum, uneven terrain, and consistent high-impact connections, helping operators make their work swift and precise.
    
• Did you know baffle plates help increase an excavator’s strength-to-weight ratio? That is why Caterpillar incorporates the plates in high-stress areas like the boom, stick, and frame. Reinforcing the machine without adding significantly more weight also helps provide years of reliable performance, even in the harshest environments.
    
• The cylinder rods are reinforced with additional wear rings to help reduce oil leaks. The car body has thick baffle plates for a long service life. The thick track link has large bolt joints to help maintain bolt retention. Track rollers have a large shaft diameter to help prevent bending and oil leaks while increasing the 340s loading capacity, which means more reliable production for you.
    
• Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
    
• The center track guiding guard helps align the excavator track when traveling and working on slopes.
    
• The sloped track frame prevents mud and debris accumulation, helping reduce the risk of track damage.
    
• Auxiliary hydraulic options allow you to use a wide range of Cat® attachments.
    
• Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
    
• Match the excavator to the job with three operating modes: Power, Smart, and ECO.
    
• Smart mode automatically adjusts power for the highest fuel efficiency – less power for tasks such as swinging and more power for digging.
    
• Enhanced heavy lift mode increases system pressure to help you easily pick and place heavy material.
    
• Auto warm-up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
    
• Don’t let the temperature stop you from working. This excavator has a standard high-ambient temperature capability is 52° C (125° F) with cold start capability at –18° C (0° F).
    
• An optional battery-operated engine heater enables starting at –32° C (–25.6° F).
    
• The C9.3B engine meets Brazil Mar-1 emission standards, equivalent to U.S. EPA Tier 3, EU Stage IIIA, and China Nonroad Stage III.

    
• Sites where excavators work are typically rugged and challenging. That’s why it’s important that the 345 cab helps protect the operator as much as possible from fatigue, stresses, sounds, and temperatures of the job.
    
• Comfort and efficiency of movement help keep operators productive and alert all shift long. The standard seat is wide and adjustable for operators of virtually any size.
    
• The tip-up left console makes getting in and out of the seat easy.
    
• Two cab options – Essential and Deluxe – let you choose the level of comfort you need.
    
• The Deluxe cab package includes a heated air suspension seat.
    
• The cab is sound-suppressed and sealed.
    
• Advanced viscous mounts reduce cab vibration
    
• Control the excavator comfortably with easy-to-reach controls located in front of you.
    
• The touchscreen monitor makes it easy to access critical information and settings. Shortcut keys make it easy; two are for entertainment, heating, and air conditioning. There is also a shortcut key for apps and functions that you can set.
    
• Standard automatic climate control keeps you at the right temperature throughout your shift.
    
• Convenience features include Bluetooth® integrated radio, USB charging and phone connectivity ports, 12V DC outlets, and an AUX port.
    
• Cup and bottle holders are easy to reach, and storage spaces are located conveniently throughout the cab.
    
• Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles.
    
• Not all features are available in all regions. Please check with your local Cat® dealer for specific offering availability in your area.

    
• The 345 uses a keyless push-button engine start. This adds security for the machine by using Operator ID codes to limit and track machine access. Codes can be entered manually via an optional Bluetooth key fob.
    
• Most machine settings can be controlled through the high-resolution touchscreen monitor. It offers several languages and is easy to reach from the seat – no twisting or turning.
    
• Operating can be made easier with the touch of a joystick button. The joystick function can be customized through the monitor. The joystick pattern and response can be set to match operator preference. All preferences are saved with the Operator ID and restored at login.
    
• You can also add an auxiliary relay to power on or turn off a CB radio, beacon light, or other attachment so you don’t have to take your hands off the joysticks.
    
• Program up to four depth and slope offsets so you can easily get to grade without a grade checker – saving time and enhancing safety on the jobsite.
    
• Operator coaching is an in-cab system that recognizes specific opportunities for operators to be more productive and prevent unnecessary machine wear and tear.
    
• Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips on the touchscreen monitor.
    
• Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.
    
• Not all features are available in all regions. Please check with your local Cat® dealer for specific offering availability in your area.

    
• The 345’s extended and synchronized service intervals and reduced hydraulic oil capacity help you save time and money.
    
• The excavator is auto-lube ready with built-in mounting points; an available auto-lube retrofit kit provides additional hardware to mount a grease pump and line guards – all to help do the job of lubing safer, cleaner, and trouble-free.
    
• Boost productivity with proactive service reminders. The Integrated Vehicle Health Management system alerts the operator with step-by-step service guidance and parts needed so you don't experience unnecessary downtime.
    
• Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
    
• Fuel and engine oil filters are accessible from the upper platform and synchronized to be changed at 1,000 hours.
    
• The latest hydraulic oil filter provides high-quality filtration performance and features anti-drain valves to keep oil clean when the filter is replaced, and the 3,000-hour extended replacement interval offers efficiency and convenience.    
    
• Scheduled Oil Sampling (S·O·SSM) ports with extended sampling intervals are on ground level, simplifying maintenance and allowing for quick, easy sample extraction for fluid analysis.
    
• Using Cat® genuine oil and filters and doing typical S∙O∙S monitoring will extend the current service interval, giving you more uptime.
    
• The high-efficiency hydraulic fan has a programmable automatic reverse function to keep cores free from debris, eliminating the need for any operator interaction.
    
• The advanced air intake filter with pre-cleaner has a high dust-holding capacity.
    
• The latest engine air cleaners with an integrated pre-cleaner surpass radial seal air cleaners' lifespan.

    
• Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
    
• A travel direction indicator helps operators know which way to activate the travel levers.
    
• A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.

Steady Market Value
Heavy machinery loses its market value over time as it accumulates wear and usage, meaning you can expect a marked decrease in value if you ever try to sell it.

However, the market value of used Cat products is relatively stable, so even if you purchase used equipment, the value tends to remain steady.

When given proper maintenance and care, a new or used Cat machine can help you maximize your productivity and profitability.

If you prefer buying used equipment, shopping the Caterpillar brand is a great option to ensure you get the most out of your investment.
